A head includes: a head unit; and a wiring film configured to be connected to the head unit. The wiring film includes: a flexible substrate; a first IC provided on the flexible substrate; a second IC provided on the flexible substrate; a first wire provided on the flexible substrate to connect the first IC and a first contact portion of the head unit; a second wire provided on the flexible substrate to connect the second IC and a second contact portion of the head unit; and a third wire provided on the flexible substrate. The first IC has a long side extended in a predetermined direction and connected to the first wire, the second IC has a long side extended in the predetermined direction and connected to the second wire, and the first IC and the second IC are aligned along the predetermined direction to be apart from each other.

A liquid discharge head includes: a first pressure chamber group formed by pressure chambers arranged in a first direction; a second pressure chamber group formed by pressure chambers arranged in the first direction, and disposed side by side with the first pressure chamber group in a second direction; a first common channel extending in the first direction and communicating with the pressure chambers composing the first pressure chamber group; a second common channel extending in the first direction and communicating with the pressure chambers composing the second pressure chamber group; a first dummy pressure chamber disposed on one side in the first direction relative to the first pressure chamber group; and a second dummy pressure chamber disposed on the one side in the first direction relative to the second pressure chamber group.

A liquid ejecting head unit includes a first connector configured to be coupled to an external wiring member. The liquid ejecting head unit includes a wiring board having the first connector, a housing for the liquid ejecting head unit, the housing having an opening through which the first connector is exposed outside and having a housing space accommodating the wiring board, and a flexible member in the housing space. The flexible member separates the housing space into a first space that has at least a portion of the first connector and the opening and a second space that is larger than the first space.

A water-repellent member includes a base layer formed on the substrate, projections dispersedly arranged on the base layer, a first water-repellent material provided on the base layer in contact with the base layer, and a second water-repellent material provided on the projections in contact with the projections. The first water-repellent material and the second water-repellent material are perfluoropolyether compounds. An oxygen concentration of the base layer is lower than an oxygen concentration of the projections.

In a printhead control circuit causing a printhead to execute printing, the printhead performing abnormality detection in response to a first signal inputted to a second terminal in a state in which the potential of a first terminal is a first potential and a second signal inputted to the second terminal in a state in which the potential of the first terminal is a second potential, one of the first and second potentials is higher than the potentials of the first and second signals, and a signal circuit is configured to output the first and second signals. The signal circuit outputs the first signal to the second wire electrically coupled to the second terminal in a state in which the first wire is being supplied with a first voltage signal at the first potential and outputs the second signal to the second wire after outputting the first signal in a state in which the first wire is being supplied with a second voltage signal at the second potential, which is different from the first potential, to cause the printhead to execute the abnormality detection in response to the first signal, the second signal, the first voltage signal, and the second voltage signal.

The head chip includes an actuator plate having ejection channels and non-ejection channels extending in a Y direction and arranged alternately in an X direction, an intermediate plate overlapped with the actuator plate in a Z direction, and provided with communication holes communicated with the ejection channels and through holes communicated with the non-ejection channels, and a nozzle plate overlapped with the intermediate plate in the Z direction in a state of closing the through holes, and provided with nozzle holes which are communicated with the communication holes, jet liquid contained in the ejection channels, and are formed at positions corresponding to the ejection channels. The non-ejection channels are communicated with an outside of the head chip. The through holes are each disposed at an inner side in the X direction of the inner surfaces extending in the Y direction of the non-ejection channel viewed from the Z direction.

A printed textile includes a base textile and a layer. The base textile includes first and second surfaces. The first surface includes a first area and a second area. The layer is located on the first surface, and contains pigment particles. A first loop height is defined as a largest height of the printed textile when the printed textile is folded with a crease at the first area. A second loop height is defined as a largest height of the printed textile when the printed textile is folded with a crease at the second area. The second loop height is no more than 1.3 times as large as the first loop height.

Laser jetting of droplets of a viscous material, such as an ink, is performed by coating a layer of ink on a mesh-like transport screen, with the ink being retained within spaces of the mesh-like transport screen. The ink-coated mesh-like transport screen is conveyed to a working area and a laser beam is used to heat the ink within the spaces of the mesh-like transport screen, thereby causing ink droplets to be jetted from the spaces of the mesh-like transport screen. Structures are formed on a receiving substrate arranged near the working area by jetting the ink droplets, either in an aggregation or sequentially, across a gap from the mesh-like transport screen to the receiving substrate and displacing the mesh-like transport screen and the laser beam relative to one another at times between the jetting of the droplets, or by directly printing ink droplets onto the receiving substrate.
